# Enable optional maintainer mode (off by default)
dnl AM_MAINTAINER_MODE turns off automatic reconstruction of the build
dnl files if the source build files have changed. A developer will want
dnl those automatic reconstructions to happen so that changes to the
dnl build system are actually carried out. However, a user might not
dnl have the tools required to reconfigure and the need for
dnl reconstruction might be spurious if the last-modified date is set
dnl incorrectly on the build files.
dnl
dnl Passing the option [enable] to AM_MAINTAINER_MODE makes the
dnl non-reconstruction feature available, but only when turned on by
dnl passing the option –disable-maintainer-mode. This option is
dnl apparently useful to some package distributors.

dnl that GNU-specific files like NEWS, README, AUTHORS and ChangeLog are

dnl -Wall: set Automake to emit all warnings it can. Is NOT RELATED to setting
dnl warnings for other tools. For example, it wil not make the compiler
dnl get a -Wall option.
dnl subdir-objects: Put object files in a directory structure based on
dnl the directory structure of the source files. This way, two source
dnl files with the same name in different directories do not conflict.
